A customer has enabled port security on a DECrepeater 900TM to disable port from an intruding MAC address. Say the port locks out after a few days. Then we look at the intrusion log (by clicking on the broken lock ICON) and we see actual date and time of break-in detection. Where does this actual time come from? In out case it is OFF by about 10 or 12 hours roughly ? So we see the month/day/year hh:mm:ss - the actual time in the intrusion log and the intruding MAC address as well. I can't see anywhere in the DEChub 900 Management Module Menu where you can set date and time on the DEChub 900, in which are DECrepeater 900 is plugged in. Nor can I see any place where I can set date and time on the DECrepeater 900TM Module Menu. Alphonse

4368.1 | Repeater keeps sysUpTime only...not time-of-day | NETCAD::PAGLIARO | Rich Pagliaro, Networks BU, HPN | Mon Apr 21 1997 10:54 | 18 |
Neither the repeater nor the DEChub 900 use internal time-of-day clocks. The repeater itself logs only the value of sysUpTime at the time the intrusion violation occured. sysUpTime is defined as "the time (in hundredths of a second) since the network management portion of the system was last re-initialized". While I am very familiar with how the repeater works, I am less familiar with how clearVISN MCM displays the information. I assume MCM uses the time-of-day clock of the system on which it is running and combines this information with the intrusion log sysUpTime timestamp (as well as the current value of sysUpTime) to display the time and date of the break-in detection. I would first verify that the time-of-day clock on your system running clearVISN is set correctly. Perhaps someone on the clearVISN team can provide more details. -Rich | |||||

Rich's suggestion of looking at the clock on the station running clearVISN is a good one, but for what it's worth, some repeaters have a bug which causes their sysUpTime to lag by about 2%. This bug will be fixed in future firmware releases. This error can account for a 1.5 hour lag in three days. If you're looking at the log right after the port locks, then never mind. If you're looking after "a few days" then "a few days" would have to be about 20 days in order for your problem to be explained by this bug. -Shawn |
